While the invention as disclosed in the parent application is embodiedin a machine for adding numbers, the principles and construction may beusefully employed in machines for various other purposes.

' Therefore, in the accompanying drawings and description, the addingmechanism is omitted. I

Like letters of reference refer to like parts in the several figures.

stantially 'in line I avenues General construction 1 represents the mainframe of the machine which may so as to support the working parts of themachine.

5 (Fig. 2) represents the main gear segments, which in the parentapplication are utilized to operate suitable accumulating mechanism andwhich in the present instance are used to move type carriers to positiontheir various types. Each of these gear segments is provided at itslower end with a rearwardly projecting arm 6 which is-pivoted lgosely ona transverse supporting rod 7.

This rod is mounted with its ends on the upper ends of two rock arms 8which turn loosely with their lower ends on a transverse rock shaft 9.The rock-arms 8 are connected bya transverse bar 10 which compels thetwo arms to move back and forth together. In the normal position of thegqear segments when the machine is at rest tese segments areretractedrearwardly and are elevated.

The gear segments are yieldingly held backwardly by means of springs 11(Fig. 9) connecting the rock-arms 8 with a stationary part of the frame.Fig. 9 shows one of the springs 11' connecting one of the rock-arms 8with a transverse stationary bar 12 in the rear part of the machine. Thegear segments are moved forward by means of a shifting rock-arm 1.3.,which is preferably secured to the right hand rock-arm 8 and projectsrearwardly. 'lUponraising the shifting rock-arm 13, the rock-arms 8 andgear segments 5 are swung forwardly while upon swinging the shiftingrock-arms downwardly, the rock arms 8 and gear segments 5 are swungrearwardlv.

1a (Fig. 2) represents a cam whereby the gear segments are movedforward. This cam is mounted on the upper portion of a verticallyswinging rocking frame 15 which is arranged on the right hand side ofthe machine. This cam is provided at its front end with an incline orcam face 16 and at its rear end with a concentric face 17. When the camis in its rearmost or retracted position, its incline stands in rear ofa roller or projection 18 on the rear end of the shifting arm 13, asshown in Figures 2, 7, and 14:. Upon swinging the rocking frame 15, sothat the cam I l moves forwardly, the incline of the latter engagesunderneath the roller 18 and raisesthe arm 13, thereby moving the arms 8forwardly. When the roller 18 has been raised to the top of the inclinethe concentric portion of the cam engageswith the roller during thecontinued forward movement of the cam and the latter does not shift thegear segments any further forward.

When the rear end of the concentric face 17 of the cam passes forwardlyfrom underneath the roller 18, the constant pull of the springs he ofany suitable construction an part of thero'ciiing'frame 15, as shown inFig- 13 and the parts conroller 18 which lifts said incline, and at theend of the backward movement of the cam,

the latter clears said roller and drops behindthe same, as shown inFigure 2, preparatory to again raising the roller 18 and connectingparts during the next forward movement of the cam 14.

For the purpose of permitting the front end of the cam to rise so as toclear the roller 18, this cam is pivoted at its rear end to the rearportion of the rocking frame 15. The

upward and downward movement of the.

ront end of the'camis limited by means of a lug l9 projecting from theside of the cam engagi g with a slot in the adjacent ures 14 and 32.

The rocking frame 15, is secured with its lower portion to a transverserock-shaft 20 journaled in the-main frameand provided outside of theframe with a hand crank 21, as shown in Figure 14, whereby this shaft isrocked and the parts connected therewith are operated. 1

The gear segments 5 are raised to'their highest position by means of areturn or lifting bar 22 which extends transversely underneath all ofthe arms 6 of the gear segments and which is connected loosely at itsrear ends with the transverse rod 7 by lifting plates 23. 24 representstwo shifting arms which are mounted loosely at their rear ends on therock-shaft 20 and which support at their other ends a transverse'bar 25which transverse bar is connected at its ends, by two links 26, with thelifting platis 23, whereby upon raising the shiftin arms 24, the liftingbar 22'is caused to raise t e gear segments and the other partsconnected therewith resting on said bar. Upon depressing the transversebar 25, the lifting bar 22 is moved downward ly and the gear segmentsresting thereon are permitted to move downwardl with the bar until thesegments are arrested Each of the gear segments is held in contact withthe lifting bar 22 by a spring 27 which connects the arm of the segmentwiththe transverse bar 25. If the downward movement of the gear segmentis arrested while the shifting arms 24 continue to move downwardly, thelifting bar 22 is moved away-from the underside of the arm of the gearsegment and the spring 27 is strained.

The transverse bar 25 is arranged in one end in a segmental notch 28formed in the front part of the rocking frame 15, shown in Figrockingframe 15, this card ing shaft 20 constitute the main moved the gearyieldingly ures 2, 'Z, and 14, and its opposite end is arranged in asimilar segmental notch 28, formed in a rocking frame 29 (Fig. 14) whichis-secured to the operating shaft, 20 on the left-hand side of themachine. The rocking frames 15 and 29 together with the operatoruniversal operating fraine of the machine.

hen the machine is at rest, as shown in F lgure 2, the transverse bar 25engages with the front side of the notches 28 in the rock ing frames 15and 29. Upon turning the rocking shaft 20 forwardly by means of itshandle 21 in the direction of the arrow, Figure 2, the rocking framesare moved forward 1y during the first part of the movement inde pendentof the transverse bar 25. The latter remains at rest until the inclinedfront end 16 of the cam 14 has raised the arm 13 and segments, duringwhich movement the rocking frames move idly the extent of their notches28 along the ends of the bar 25 without disturbing the latter. After thegear segments have been moved forward the continued forward movement lof the rocking frames causes the rear ends of their notches 28 to engagewith the bar 25 and depress the same, thereby causing the lifting bar 22to be moved downwardly and strain the springs 27. This causes all of thegear segments which are free, to be moved downwardly and to continuetheir downward movement until he are arrested. After the segments havebeen arrested in their downward movement, they remain in this positionwhile the locking frames complete their forward movement. At the end ofthe forward movement ,of the rocking frames, the roller 18 of the rockarm 13 drops 05 from the rear end of the concentric part of tion.

30 represents a number. of elbow-shaped controlling arms, which formpart of the devices whereby the downward movement of the gear segmentsis controlled. One of these arms is arranged along the left-hand side ofeach gear segment and consists of an upright front (part and ahorizontal lower part which exten rearwardly from the lower end of theupright part, thereby leaving a clear space in rear of the upright partof the controlling lever, as represented in Figures 1, 2, 'Z', 13, 33and 34.. The rear end of the lower the uppermost as shown in Fi art ofeach controlling arm is mounted loosey on a transverse su porting bar31, while the-upper end of its out or upright part is loosely connectedwith the up er portion of its companion gear segment. his looseconnection permits the controllingarm and the gear segment to swingfreely about their in dividual axes, but out of line, and alsopermitsthe gear segment to move forward and backward. In osition of the"controlling arms the same ear with their upper ends against atransverse stop bar 32, as shown in Figure 2, which limits the upwardmovement of thesearms. Each controlling arm is provided on the rear partof its upper end with a locking lug 33, and on the front part of itsupper end with a stop lug 34, both of which lugs project toward the leftand are preferably stamped out of one piece with the controlling arm.

The operation of the recording devices is controlled by a number ofelbow-shaped key levers which are arranged side by side and pivoted to atransverse Each key lever is provided with anlower actuating arm 36which projects forwardly and an upper sto arm 37 which projects upwardlyalong the eft hand side of one of the controlling arms and gearsegments, as represented in Figures 2, 7 13 and 33. Each of thesekey-levers is provided on the rear side of its stop arm with a lockingshoulder 38 which is adapted to engage with the locking lug 33 of thecontrolling arm when the latter is elevated'into its highest positionand the key-lever is in its fully retracted position,

ure 2. When the parts are in this position, t e key lever holds thecontrolling arm against downward movement and the latter holds the gearsegment against downward movement. If the gear segment while so heldagainst downward movement is moved forward. and the rocking frames areturned forwardly for depressing the gear segment, the spring 27 of thissegment will be strained without, however, shifting the segment. At theend of this forward movement of the rocking segments, the roller 18 ofthe rock arm 13 drops ofi from the rear end of the cam 14, the gearsegment islmoved rearwardly, and then the rocking frames movebackwardly.

The upper arm of each key lever is provided on its front side with avertical series of differential stop shoulders 39, which are arrangedste fashion and extend from the upper end 0 this arm downwardly and forwardly thereon or in other words the stop shoulders 39 are arrangedradially out of line with one another and different distances from thepivot of the key lever. These stop shoulders of the key lever areadapted to be moved forward into the path of the stop lug 34 on thecontrolling arm. The stop shoulwhich are arranged parallel supportingrod 35.

ders are arranged difierent distances from the stop lug 34; of thecontrolling arm, so that by moving different stop shoulders of the keylever into the path of the stop plug of the controller arm, the latterand the gear segment connected therewith may be arrested at diiferentpoints in their downward movement. The uppermost stop shoulder of thekey lever is most remote from the stop lug of the controlling arm andtherefore requires the greatest forward movement of the key lever, inorder to bring this stop shoulder into the path of this stop lug.

The stop shoulders of the key levers are so arranged that the distancefrom the stop shoulders to the path of the stop lug 34' gradually growsless from the uppermost stop shoulder to the lowermost stop shoulder. Byturning the key lever forward more or less and moving one or the otherof its stop shoulders into the path of the stop lug 34 of thecontrolling arm, the distance which this arm descends can be varied,thereby varying the number of spaces which its gear segment turns.

M az'n number key mechanism 40 represents the main ke s whereby the keylevers of the main recor ing mechanism are operated, and which areguided with their depending stems in the top 41 and bottom 42 of thekey-board. As shown in the drawings, nine longitudinal columns of thesekeys are arranged transversely side by side. The first column on theright hand side of the machine contains eight keys and representsfractions of one-eighth of a cent, the next column toward the leftcontains nine keys and 'reprresents cents and the remaining columns ofeye toward the left each contains nine keys and re resents progressivelyhigher orders of num ers according to the decimal system, so that theregistering keys in the last or left hand column represent hundreds ofthousands of dollars.

The lowest number of the several columns of keys are arrangedtransversely in a row on 'the rear part of the keyboard and thecorresponding higher numbers of the several columns are arrangedlikewise in transverse rows and progressively in their order toward thefront end of the keyboard.

Each of the registering keys is yieldingly held in an elevated positionby a spring 43 surrounding-the stem of the key and connected at itsupper end to the key and bearing with its lower end against the bottomof the keyboard. The upper movement of each key is imited by a shoulder44 formed on the up or art of its stem and engaging with the un ersideof the top of the key-board, as represented in Figures 20 and 22.

The downward movement of all of the keys is substantially the same, butthe arrangement of each-column of keys lengthwise of the lower actuatingarm 0 each key lever tances. The keys having the lowest numbers j,

bear against their respective key levers nearest the pivot andconsequehtly the levers are thereby thrown the greatest distance, andthe uppermost stop shoulders are shifted into the path of the stop lug34 of the respective controlling arms. The throw of each key lever uponpressing any one of its keys is so adjusted that the proper stopshoulder on its upper arm-is moved into the path of thestop lug 34 ofthe controlling arm and the downward movement of the respective gearsegment is arrested after having turned a number; of spaces correspondinto the number of the key which is depresse 'A slip or loose connectionis provided between the controlling arms and the gear segments of higherdenominational order which in the parent application is utilized'forcar,- rying in the accumulating mechanism, However, in the presentapplication such sli connection might be dispensed with an any meansprovided whereby-the gear segments may drive the controlling'arms.

As shown in Figures 1, 2,and 7, each controlling arm is provided at itsupper end with upper andlower guide faces 47 and 48 and its lower guideface is engaged by a lower guide lug 46 on the adjacent gear segment,the same as in the coupling between the controlling arm and the segmentof the initial registering device.

When a key lever is actuated and the machine operated, the controllingarm related to said key lever descends until stopped by said key lever,and during the last portion of the operation the controlling arm and keylever are returned to their normal positions.

When the controlling arm has been retracted to its highest position, theadjacent key lever is moved into its normal retracted position, so thatits locking shoulder 38 engages with the locking lug 33 ofthecontrolling arm and locks the latter against downward movement. Thereturn movement of each key lever is preferably effected by a spring 60which connects the upper arm of the key lever with the transverse shaft9, as shown in Figures 2 and 7, or some other convenient part of themachine. The lower guide lug of the gear segment is not absolutelynecessary because the weight of .the parts connected with thecontrolling arm and arranged in rear of its pivot is sufiicient to raisethe arm, but it is preferable to employthis lower guide lug 46 on thegear segment because it compels the arm to raise with the gear segmentand avoids displacement of these parts with reference to each other, andalso serves as a stop to limit the upward movement of the gear segment.

Recording mechanism For the purpose of recordin numbers, a recordingmechanism is provi ed which is constructed as follows 140 (Figs. 1, 2, 79, 14, etc.) represents a printing roller or platen which is arrangedtransversely in the upper, rear part of the machine and under the lowerside of which the sheetor .other article is placed which receives therecord. 141 represents a number of'type se ments which arearranged-transversely side by side below the platen and which arepivoted at their front ends to the supporting bar 31 upon which the rearends of t e controlling arms are pivoted. Each of these type segments isprovided at its rear end with a segmental row of. pa carriers 142 whichare capable of moving radially back and forth on the type segment.

Each of the type carriers is provided at its rear end with a type and isguided upon the type segments by means of screws or rivets 143 (Figs. 3,29 and 30) secured to the type carrier and arranged in radial slots 144formed in the type segment. Each of the type carriers is held in itsinward. or retractmg position by means of an S-shaped spring 145, whichis arranged between the carrier and the type segment and is secured withone end to the carrier and with its other end to the type segment, asshown in Fi ures 29 and 30. Upon raising or lowering t e type segmentany one of its type can be broughtto the printing point or line, andupon striking the back or lnner end of the type carrier, when the sameis in line with the printing point, the type carrier will be drivenoutwardly and its'type will produce an impression on the sheet supportedby the platen.

After'the carrier has received the blow for driving the same against theplaten, the car rier is again quickly retracted to its innermostposition by means of its spring.

Each of the type segments is connectedwith one of the controlling arms,so that upon depressing a controlling arm and the re 'ster-f mg gearsegment connected. therewit the companion type segment will be raisedand present one of its type to the printing point.

For convenience in operating-the machine,

. the keys are separated a considerable distance on the key-board and inorder to produce a compact record, the printing segments are arrangedcloser together than the keys. .In order to permit of this arrangement,each type segment and its corresponding controlling arm are connected bya connecting arm 146,

as represented in Figures 1, 2 andv33. The connecting arms of thecentral controlling arms and type segments are comparatively straight,but the connecting arms of the outer type segments and controlling armsare arranged obliquely, the degree of this obliquity graduallyincreasing from the central type its type on the connecting arms 146 ofthe outer controlling arms.

The types on each type segment are arranged to correspond with the teethand numbers of its companion gear segment, the zero type being at theupper end of the series and the progressively higher digits arranged intheir order downwardly from the zero type. When the registering gearsegment is. in its highest position, the type segment which at this timeis in its lowest position presents its zero type to the printing point.Upon depressing a gear segment, its companion type segment is raisedproportionately and presents a correspondingly higher numbered type tothe printing point.

147 represents a number of hammers whereb the type carriers are struckfor driving t e type against the platen. One of these hammers isarranged adjacent to each type segment and is provided with a head whichis arranged in front of the series of types and in line with theprinting point of the platen. Upon shifting the type segment so as tobring one or another of its type carriers to the printing line and thenoperating the hammer, the latter delivers a blow against the inner endof the particular carrier which is at the printing polnt and produces animpression of laten. The several hammers are pivoted on t e transverserod 12, arranged in rear of the segments; and each of the hammers isyieldingly held in its forward position by a spring 148 connected at itslower end to a cross bar 149 and at its upper end to a depending arm 150on the hammer.

151 represents a vertically movable trip bar or rod which is arrangedtransversely below the hammers and whereby the latter are operated. Thisbar is supported at its ends upon the rear ends of rock arms 152 whichturn loosely with their front ends on the rod 31 supporting the typesegments and controlling arms.

153 represents a number of hammer or trip pawls, whereby the hammers areretracted preparatory to delivering a blow against the t pe carrierswhich are at the printing point. ne of these pawls is arranged adjacentto each hammer 'and pivoted loosely at its lower maaeae upper end of thehammerd pawl with a lower trip lug or shoulder 156 and an'upper trip lugor shoulder 157. l/Vhen the parts are at rest, the hammer pawl 153 israised into ts highest position and the hammer is in its normal positionwith its'lower trip lug 156 below and in. rear of the hook of the hammerpawl and with its upper shoulder 15'? 1n rear of the trip face of thehammer pawl, as represented in Figures 2, 3 and 41.

Upon shifting the hammer pawl rearwardly, while the parts are in thisposition, so that its hook overhangs the lower shoulder 156 of thehammer, and then pulling the hammer pawl downwardly, the hook of thehammer pawl engages with the lower shoulder of the hammer and turns thesame so that its head is retracted from the type carrier at the printingline. As the hammer moves downwardly with the hammer pawl, the uppershoulder of the hammer comes into engagement with the trip face of thehammer pawl and. during the continued downward movement of the hammerand its pawl, this upper shoulder gradually crowds the hammer pawlforwardly with reference to the hammer by reason of the hammer and itspawl swinging on different centers. During the last portion of thedownward movement of the trip bar 151 and the hammer pawl mountedthereon, the pawl is crowded forwardly by the upper shoulder 157 of thehammer to such an extent that its hook is disengaged from the lowershoulder 156 of the hammer, thereby liberating the latter and permittingits spring 148 to throw the same quickly and deliver a blow against thetype carrier at the printing line. The trip bar 151 now rises andcarries the hammer pawl into its highest position, preparatory to againengaging the hammer for depressing the same.

158 (Fig. 3) represents a number of upright shifting arms whereby the.hammer pawls are moved rearwardly, so that their hooks engage with thelower shoulders of the hammers. One of these arms is arranged adjacentto each hammer pawl, as shown in Figures 3, 6 and 41, and is pivoted atits lower end on the trip bar 151, and its upper end is provided with aroller or projection 159 which bears against a hammer cam 160 on thelower part of the adjacent type segment, as shown in Figures 3 and 7.This hammer cam is provided at its upper end with a receding or lowportion, an inclined portion arranged below the low portion, and aconcentric or high portion arranged below the inclined portion. Eachshifting arm 158 is moved forwardly and its'roller is yieldingly held inen agementwith the adjacent hammer cam y a spring 161 connecting saidarm with a cross bar 162 secured to the rock arms 152, as represented inFigures 7 and 8. The backward movement of each hammer pawl withreference to its companion shifting arm, is limited by means of astop163 secured to the upper portion ofthe hammer pawl and engaging withthe front side of the shifting arm, as represented in Figures 3, 5 and41.

Each hammer pawl is yieldingly held in its rearmost position withreference to its shifting arm by means of a C-shaped spring 164 securedwith its ends, respectively, to the hammer pawl and its shifting arm, asshown in Figures 2,3 and 41. In the lowermost posi-" hook has passedbelow. this shoulder; but instead, the trip face of the hammer pawlslides idly against the shoulder 156 without retracting the hammer,whereby no impression of the.

particular type at the printing line is produced. If the type segment israised, so as to present one of its lower types to the printing point orline, the incline of its cam, during the first part of the upwardmovement of the segment, movesthe shifting arm 158 rearwardly togetherwith the hammer pawl yieldingly connected therewith, so that the hook ofthe hammer pawl stands over the lower shoulder 156 of the hammer. Uponnow depressing the pawl 153 the hammer will be retracted and releasednear the end of the downward movement of the pawl, and will be quicklyswung up by the spring 148 thereby delivering a blow against the type atthe printing point and producing an impression thereof.

The incline 160 of the type segment cam is so constructed that it throwsthe hammer pawl backwardly into an operative position when the segmentis raised one digit space, and during the continued upward movement ofthe segment, the hammer pawl is held in this operative position by thehigh concentric part of the segment cam. By thus constructing the typesegment cam its companion hammer pawl is not shifted when the segment isnot raised and its zero type remains at' the printing line, but thehammer pawl is shift ed into an operative position for producinganimpression, if the type segment is raised one or more digit spaces andpresents any one of its digits higher than zero to the printing line.

Automatic printing of zero 165 (Figs. 3 and 41) represents a number oftransfer or coupling fingers which enable the ciphers in a number to beprinted automatically. One of these transfer fingers is secured to eachof the shifting arms 158, as

represented in Figures 3, 7, and 41, and extends laterally toward the riht therefrom in front of the shifting arm 0 the next lower hammer pawl,as represented in Figure 22. If any one of the printing segments remainsin its lowest position, so that its cipher remains at the printing lineand the next higher printing segment has been raised for printing ahigher number or digit, the transfer finger of the higher hammershifting arm 158 while being moved rearwardly by the cam of itscompanion printing segment, is caused to engage with the shifting arm158 of the next lower hammer pawl and shift the latter backwardly, sothat its book is carried back wardly over the lower shoulder of thecompanion hammer. Upon now depressing the trip bar 151, the higherhammer pawl 153 is coupled with its hammer, whereby an impression of thecipher or zero type on the lower segment is produced on the platen atthe same time that the next higher number is printed on the platen.

If two ciphers occur in succession in the body of a number, the shiftingarm to the left of the highest order printing segment to'be operated forprinting a zero sets the hammer mechanism of said highest zero-printingsegment by means of thetransferiinger of said shifting arm, and theshifting arm of said highest zero-printing segment in turn by means ofits transfer finger sets the hammer mechanism of the printing segment ofnext lower order, etc. This operation of producing an impression of thecipher type is effectedautomatically and renders it possible to printany number of ciphers in succession in the body of a number because thehammer operating mechanism of each segment which remains standing withits upper type at the printing line is controlled by the hammeroperating mechanism of a higher type segment and in turn controls thehammer operating mechanism of the next lower type segment, if the nextlower segment presents a cipher to the printin line.

Only the ciphers elow the highest digit in the number to be recorded arethus printed automatically because the printing of a digit depends uponthe upward movement of a printing segment, thereby avoiding the printingof ciphers ahead of the highest digit in the number to be recorded. Thehammer shifting device of the segment' which prints the numbersrepresenting units of cents is, preferably, not provided with a transferfinger to operate on the hammer shifting device of the segment whichprints fractions of a cent, because it is proper that the space to theright of the lowest integer shall remain blank when no integer isrecorded therein.

The trip bar 151 is raised by one or more springs 166 (Fig. 8) whichconnectthis bar with the transverse rod 12, and the upward movement ofthe bar 151 is arrested when of the rocking frames, the front ends oftheir the hammer o crating pawls reach their highest position y atransverse bar 107 (Figs. 8, 9, and 16) which is engaged by the rearends of the rock arms 152. 168 represents a coupling hook, whereby thehammer trip devices are depressed. This hook is pivoted with its upperend to the trip bar 151 and its lower engaging end'is provided with anotch having up 'er and lower shoulders.

In the. lowere position of this hook its notch engages with a cross bar169 which is connected with the rock arms 24, as represented in- Figures2 and 7, so that the hook and the hammer operating devices connectingtherewith are actuated from the rockin frames 15 and 29, through themedium 0 the rock arms 24. In the rearmost position notches 28 bearagainst the front side of the bar 25 to which the gear segments areyieldingly connected, and the cross bar 169 bears against the rear orupper shoulder of the IlOtClQl of the hook 168, as represented in FigureU on swinging the rocking frames forwar the incline of the cam 14 firstraises the rock arm 13' and shifts the gear segments into engagementwith the dial pinions, and

after the segments have been so shifted, the.

rear shoulders of the notches 28 in the rocking frames engage with thecross bar 25, so that thereafter this bar is carried downward with therocking frames and the gear segments are depressed. During this downwardmovement of the bar 25 with the rocking frames, the companion bar 169moves down idly in the notch of the hook 168 until this bar engages withthe lower or front shoulder of this'hook. After the cross bar 169engages with the lower shoulder of the notch of the hook, the latter andthe hammer operating devices connected therewith are moved downward withthe rocking frames until these frames reach the end of their downwardmovement. During the last portion of the downward movement of therocking frames the hammer pawls are disengaged, as before described,from the retracted ham mers, whereby the latter are released and strikethe type carriers which are at the printing line. By this means, theblow of the hammers is delievered after the type segments have beenshifted into their proper position for recording the respective number.

The hammers do not follow the type carriers to the end oftheir outwardmovement but are stopped short, after delivering a blow against theinner ends of the carriers by their depending arms 150 engaging with arubber" facing 170 on the cross bar 167, as

shown in Figure 3, so that the type are moved outwardly by the impactof'the hammers and are then returned by their springs '50 as to clearthe printing surface.

N on-pn'nt mechanism When it-is desired to render the recordingmechanism ineffective, the coupling hook 168 is raised with its notchout of engagement ,with the cross bar 169, which allows the rockingframes and connecting parts to move back and forth without affecting thehammer operating devices. The con ling hook is disengaged from the crossbar y means of an elbow lever 171 secured to a transverse rock shaft172. The lower arm of the elbow lever is connected with the shaft 20 bya spring 17 3, whereby the lever and the shaft carrying the.

.same are turned in the direction for disconnecting the up er arm of thelever 171 from the hook 168, t ereby permitting the latter to engage thebar 169. v

174 (Fig. 9) represents an elbow lever arranged below the bottom of theke board and having its lower arm connecte by alineor cord 17 5 to theupper arm of the elbow lever 171. 176 represents a shifting key havingadepending stem which is guided in the top and bottom of thekey-board'and which engages with its lower end a ainst the upper arm ofthe elbow lever 1 4. Upon depressing this key the elbow lever 174 isturned in the direction for moving the rock arm 171 into engagement withthe cou ling hook 168 4 and disengaging the latter rom the cross bar169, thereby throwing the recording mechanism out of gear. Uponreleasing the key 17 6, the rock arm 171 is permitted to swingbackwardly and allow the cou ling hook to engage with the cross bar 169,t ereby throwing the recording mechanism into gear.

Duplicate painting by counterpart types For the purpose of permittingthe numbers to be printed in duplicate, for instance, when it is desiredto print an amount on a bank check, and the same amount on a stub, themachine is provided with a mechanism which is constructed as follows:

1410 (Fi s. 1, 14 and 16) represents a number of dup icate printing ortype segments which are arranged transversely in line and preferablytoward the right of the main printing segments 141, and which arepivoted loosely at their front ends on the supporting rod 31. One ofthese duplicate number printing segments is provided for each of themain number printing segments, and each duplicate segment is connectedwith its companion main segment by a U-shaped frame (Fig. 18) whichframe is connected by the upper ends of its arms 189 to its duplicateand main segment and has its crossbar 190 arranged transversely belowthe intervening segments, as shown in Figures 1, 2, 4, 7 and 18., Thecross bars 190 are arranged sufficient distances below the segments so.that each pair of connected main and duplicate .to and constructed thesame as the type carriers of its companion main segment and each ofthese duplicate segments is provided with a hammer operating devicewhich is constructed the same as the hammer operating devices of themain segments, and the same description and letters of reference,therefore apply to the details of both the main and duplicate printingsegments.

Duplicate printing inoperative If it is desired to duplicate only thesmall numbers no duplicate segments need be provided for the highernumbered printing seg ments. For the purpose of throwing the duplicateprinting mechanism out of gear when. it is not desired to print thenumbers in duplicate a horizontal movable bar 191 (Fig. 19) isprovidedwhich I is arranged transversely in rear of the hammer pawls ofthe duplicate printing segments and which is provided with a number offorwardly projecting lugs or stops 192, as represented in full lines inFigures 4, 16 and 19. Upon shifting this bar, so that its stops stand inrear of the duplicate hammer pawls, as shown in full lines in Figure 19,these pawls are prevented from being swung rearwardly and operating thehammers. Upon moving this bar so that its stops clear the duplicatehammer pawls,- as represented by dotted lines 192, Figure 19, thesepawls are free to be swung rearwardly by the segment cams 160 intoengagement with the hammers, so as to retract the same during thedownward movement of the pawls for producing an impression of the typesof the duplicate segments which are at the printing line. A suitable keyor finger-piece is provided, by the operation of which the bar 191 isshifted into effective position.

Horizontal ruling or cross ruling upon the sheet or surface whichreceives the record, the following mechanism is provided:

193 (Figs. 2, 7, and 17) represents the lowermost type carrier of eachof the number printing segments, each of which is provided at its rear.end with a horizontal ruling type. Each of these ruling type carriersis constructed the same as the number type carriers with the exceptionthat the front end of each ruling type carrier is widened horizontally,preferably, in both directions in the form of the letter T, as shown inFigure 17 and the ruling type extends transversely from end to end ofthe widened ,part of',this carrier, so that the ruling types, whenplaced transversely in line and driven against the platen, will producea practically continuous line transversely on the recording surface.Each of the number key levers is provided on the front side of its upperarm with a ruling stop or shoulder 194, which is arranged one spacebelow the lowermost number registering stop or shoulder 39.

Upon swin ing the key levers, so as to bring their ruling s oulders 194into the path of the lugs 34 of the controlling arms,-.the lattertogether with the gear segments connected therewith are depressed uponmoving the rocking frames 15 and 29 forwardly, until the stop lugs 34 ofthe controlling arm engage with the lowermost or ruling shoulders 194 ofthe key levers. When the controlling arms reach this lowermost position,the printing segments connected therewith have i been raised to theirhighest position and present The key levers are turned simultaneouslyfor bringing all of their ruling shoulders simultaneously into the pathof the stop lugs of the respective controlling arms by means of arocking plate 195 which is arranged transversely in front of the lowerarms of the key levers and overhangs the front ends thereof, asrepresented in Fi 'ures 2, 7 and 22. This rocking plate is secure to atransverse rock shaft 196 which is 'ournaled in the frame .key isprovided with a depending stem which is guided in the top and bottom ofthe keyboard and which engages against the rear end a of a 'rock arm 199projecting rearwardly from the rock shaft 196, as represented in Figure9. For the purpose of producing horizontal.

Upon .depressing this key, the rocking plate 195 is turned in thedirection for depressing the front arms of all. the number key leversand bringing the ruling shoulders 194 on the upper arms thereof intoposition for arresting the type segments during their upward movementwhen the ruling types arrive at the printing point.

In order to prevent the gear segmentsfrom moving forward during thecrossruling operation the position of the cam 14 is reversed at the sametime that the plate 195 is depressed.

The mechanism whereby cam 14 is reversed is constructed as follows:

The cam 14 drops into its operative position by gravity, and is providedin rear of its pivot with a tail 75 which is depressed when it isdesired to lift the cam into its inoperative position.

76 is a shifting lever which is pivoted at its lower end and is normallyturned so that its upper end is disengaged from the rear side of thetail on the cam 14, by a spring 77, as shown in Figures 2 and 7. 82,Fig. 9, represents a line or cord connected to lever 76 above its pivot,and 1961 represents a line or cord for operating cord 82.

In the parent application several 'cords operate the cord 82, but forthe purpose of the present application, the members-82 and 1961 might bea single cord.

The cord 1961 is connected to arm 1960 fast on a shaft 196, operable bythe cross rule key 198.

When it is desired to produce horizontal ruling on the recordingsurface, the key 198 is depressed, thereby raising the cam 14 into aninoperative position, and moving all the number key levers with theirruling shoulders 194 into the paths of the stop .lugs of the controllingarms. Upon now moving the handle 21 (Fig. 14) forwardly the consequentrocking of the frames 15 and 29 first causes the gear segments and theircontrolling arms to be moved downwardly until arrested by the rulinshoulders 191 of the key-levers, in whic position of the parts, theprinting segments have been raised with their ruling types to theprinting line. The continued forward movement of the rocking framesoperates the hammer-tripping mechanism and produces an impression of theruling types on the record surface; upon moving the handle 21 backwardlythe parts resume their normal position.

Instead of producing cross ruling by means of a transverse row ofindependent types, this ruling ma be effected by a separate ruling late200 Fig. 37) which extends transversey along the entire width of thespace to be ruled. In this modified construction of the horizontalruling device, the ruling plate may be supported by upright arms 201from a transverse bar or shaft 202, and may be operated by any suitablemechanism.

Vertical ruling Mechanism is provided whereby vertical ruling may beroduced on the recording surface, this mec anism being constructed asfollows: v l

203 (Figs. -1-,-14,.-16, and 28) represents an upright ruling leverwhich turns loosely on the supporting bar 12 and which is arrangedbetween the dollars and dimes printing segments: The upper arm of theruling lever is provided with a vertical rulingblade 204 (Fig. 28) whichis arranged close to the platen when in its upper position. The rulinglever is yieldingly held in this position by means of a spring 205connected with the lower arm of the ruling lever and the movement ofthelatter toward the platen is limited by the engagement of its lowerarm with the rear side of a rubber buffer 206 on the cross bar 167similar to the rubber 170. 207 represents a pawl whereby the rulinglever is retracted and then released for permittingthe same to deliver ablow against the recording surface for producing a vertical rulingimpression thereon. This pawl is pivoted at its lower end on the crossbar 151 and is yieldingly held with the hook 208 on its upper arm inengagement with a shoulder 209 on the ruling lever by means of a spring210 which connects the lower arm of the ruling lever with the rod 162.

In the uppermost position of the bar 167 the ruling pawl engages theshoulder of the ruling lever and upon depressing this bar, the rulinglever is pulled downward by the ruling pawl. During this downwardmovement of the ruling lever and pawl, the front side of this leverengages with the upper arm of the pawl and gradually crowds the awlforward until the pawl is disengaged rom the shoulder of the lever. Whenthe ruling lever is thus released from the pawl, the lever is quicklyturned by the spring 205 in a direction for throwing its upper armupwardly, whereby its blade delivers a blow against the recording sheetor surface on the platen and produces a ruling im ression thereon.During the last portion 0 the subsequent upward movement of the rulingpawl 207 its hook again engages over the shoulder of the ruling lever.This construction of vertical ruling devices produces the verticalruling in sections by successive blows of the ruling blade.

If desired vertical ruling may be produced by holding a stylus or leadpencil 211 against the recording surface by means of a stationary holder212, as represented in Figure 38, whereby continuous ruling is producedon the recording surface or sheet as the sheet is fed past the same.

Vertical ruling may also be produced by a ruling disk 213 arranged tobear with one side against the recording surface and an inking wheel 214supplying the ink to the edge of the ruling disk, as represented inFigure 39.

' Word printing mechanism For the purpose of permitting words to belocking lug printing segment of the main number record ing mechanism.This segment is provided with anumber of radially movable carriers 1420,(Figs. 8 and 16) which are constructed the same as the carriers of thenumber print- 1 machine is. designed for use in a restaurant,

the words Soup, Vegetables, Meats, Dessert, and other words peculiar tothis business-may be used.

The position of the word-type segment is controlled by a key lever 3600,Figure 8,'which turns on the bar 35, is similar to the number keylevers, and is provided on the front side of its upper arm 3700 with avertical series of differential stops or shoulders 3900 which areadapted to be engaged by the stop lug 3400 of a controlling arm 3000;and lever-3600 is also provided with a locking stop or shoulder 3800which is adapted to be engaged by a 3300 on the controlling arm, asrepresente in Figure 8. The controlling arm 3000 is connected with theword-printing segment by a connecting bar 1460. The stop shoulders onthe upper arm of the wordkey lever are so arranged that upon swingingthis lever so as to carry difierent shoulders into the path of the stoplug on the controlling arm,,the latter will be arrested at differentpoints in its downward or forward movement and the word-printing segmentconnected therewith will be stopped at different points in its upwardmovement and present the particular Word type to the printing pointwhich corres onds with the shoulder or stop on the wordey lever.

The upward movement of the controlling arm 3000 is limited by its rearlocking lug 3300 engaging with the stop bar 32 which arrest the upwardmovement of the controlling arms 30 of the auxiliary recordin mechanism.The downward movement 0 the controlling arm 3000 and the simultaneous upward movement of the word printing segment is effected by a spring 215which yieldingly connects this arm with the bar 25 to which theregistering gear segments are connected.

216, Fig. 1, represents a row of word-keys having depending stems whichareguided in the top and-bottom of the keyboard'and which engage againstthe upper side of the front arm 3600 of the word ey lever at differentdistances from the fulcrum thereof. Upon depressing any of the wordkeys, the work-key lever will be turned the pro er distance to bring itsproper stop shoul or into 'ent invention.

the path of the stop lug of the companion controlling arm and arrest theword-type segment during its upward movement, when the word-typecorresponding with the word of the depressed key has reached theprinting line. When the respective word-type is in this position thesame is driven against the recording surface for producing an impressionthereon, at the same time that the printing of the numbers by thenumbering printing segments, is effected. The word-types are drivenagainst the platen by a hammeroperating mechanism which is constructedthe same as the hammer-operating devices of the number printingmechanism, and the same letters of reference are therefore used todenote the same. The word-key. lever is yieldingly held in its normalposition by a spring 600.

Auxiliary printing mechanism .structed as follows 5000 (Figs. 1 and 25)represents a number of auxiliary gear segments which are mounted on thetransverse rod 7 and are movable forward and back therewith. Each gearsegment 5000 is connectel with a res ective controlling arm 3001 (Figs.1 and 25) in substantially the same way that the main gear segments areconnected to their controlling arms, except that the auxiliarycontrolling arms are capable of moving independently of their correlatedgear segments. This last feature, however, forms no part of the presand25) represent the lower and upper arms respectively of auxiliary keylevers which are operated by auxiliary keys 401 (Fig. 1),

and which control the operation of the auxiliary recording mechanism.

The detail construction of. the gear segments, printing segments, keylevers, and the parts co-operating therewith of theauxiliary recordingmechanism, is substantially the same as the construction of analogousparts in the'main recording mechanism, except as elsewhere mentioned,and the same letters of reference are therefore employed in most casestov denote like parts in both of these sets of mechanisms.

In the drawings, two auxiliary key levers and related parts are shown,but additional recording devices may be emplo ed if it is desired toincrease the capacity 0 the machine. H In the auxiliary recordingmechanism the gear segments are not rovided with lower stops 46 likethose of t e gear segments of the main recording mechanism, so that theauxiliary controlling arms may move down-
